Specfication of Letters Patent.

Application flled September 27, 1906. Serial No. 386,453.

To all whom it may concern:

Be it known that I, GEORGE W. RowE, of Hampton, in the county of Elizabeth City, State of Virginia, have invented certain new and useful Improvements in Sifter-Boxes, of

-which the following'is a specification.

'My invention relates to containers for 'granular or ulverulent substances generally,

and has for its object the provision of means for normally confining the contents'of the receptacle within it and of discharging the contents therefrom, at will. i

My device is adapted, for culinary and other' uses, to contain salt, pepper or other owdery substances, and provides means for holding the contents securely in place, or for liberatmg them by sifting, ,through a number of perforations provided, vas usual, for that purpose.

In the accompanying drawing, which constitutes a part of this application, Figure I is a side elevation of my invention, in one form of embodiment, complete. Fig. II is a' diametrical, Vertical section of the subject matter of Fig. I. Fig. III is a top plan view of the discharge end of the box, showing in full lines the apertures therein closed, and in dotted lines, the same open. Fig. IV isl an inside view of the subject matter of Fig. III. Fig. V is an inside view of the discharge end or cover of the box, With the discharge-controllinglate removed. Fig. VI is a view of the at side of the discharge-plate, detached. Fig. VII is a side elevation of the push -rod assembled with its dischargeplate, but with the discharge end of the box or cover removed. w

Referring to the numerals on the drawing, 1 indicates an ordinary cylindrioal box, presented by Way of example of any container of any preferred sha e and material. This container is provide with a perforated discharge end 2, which, in the form of embodiment illustrated, referably consists of a detachable cover, w ose skirt 3 telescopes upon the end 4 of the box 1. In this form of embodiment frictional enga ement between the members 3 and 4 is relie upon to secure the cover to the box, but any preferred method of uniting the cover and the box, if the cover be made separable from` the box, may be employed. The cover 2 is preferably provided.

with a series of perforations 5, which may be disposed in any preferred form or order of arrangement.

Fitting snugly against the inner face of 'the cover 2, I provide a discharge-plate 7,

which is held to place as by a rivet 8. The dischargelate 7 is so constructed with reference to t e perforations 5 in the cover as by its reciprocatory movement to alternately cover and unoover the aperture 5 in the cover. For this purpose, it may be provided with a series of apertures 9, preferably a.

little larger in diameter than the apertures 5, but corresponding to the apertures 5 in their relative disposition; but it is obvious that the apertures 9 ma be widely modified in sha e, provided on y that the form of the disc arge-plate be such as may adapt it to the function of covering and uncovering the apertures `5 in the cover through the reciprocatory movement of the discharge-plate. The reclprocatory movement of the dischargelate with reference to the cover is conveniently provided for by the em loyment of a slot 10 in the cover, through w ich the rivet 8 passes.

The discharge-plate 7 -is normally but yieldingly held by suitable means for the purpose in the position to close the apertures 5. The means which I prefer to employ is a bow-spring 11, which may lie snugly against the inside of the cover 2 adjacent to an edge of the dischar elate. The bow-s ring is preferred, chie y, ecause it lies uno structively out of the way, occupies no considplate against the force of 'its spring, said means preferably consisting of a rod 16, secured to the rivet 8 and projecting through the side wall of the cover of the box where it I terminates in a push button 17. For the accommodation of the rod 16, if a detachable cover be employed in connection with the box, suitable recesses 19 and 20 may be provided in the box and the cover, respectively, to accommodate the rod and to afford a suitable b'earing support for it adjacent to the push button 17.

The operation of my device may be described as follows: The parts beingv assembled, as' shown, for example, in Fi .I, the discharge-plate 7 is kept driven by t e force of its spring 11 in the direction of the push button 17, thereby perfectly closing the apertures 5 in the cover 2.. In this, Which is its normal position, the contents of the box are securely confined within it. Whenever the operator Wishes to discharge a portion of the I .contents of the box, it is necessary only to press thel push button 17 to its limit of movement, said limit of movement bein predetermined to that position in which tIie apertures 5 and 9'respectively Will register; with each other. Thereupon, by inverting the boxlits contents may be sifted out through the apertures 5 after the ordinary manner of manipulating a pepper box or salt Shaker.

What I claim is:

1. The combination With a box provided With a erforated portion and With a bead, of a disc arge-plate adapted to cover and uncover said perforations, a boW-spring secured to an edge of the disohargelate, and having its ends disposed in said Eead, and means upon the dischar e-plate, operative 4from the outside of the 0x, for actuating said discharge-plate in opposition to the force of the spring.

2. The combination with a box and its perforated cover, of'a discharge-plate adapted to cover vand uneover said perforations, a ,'J

slot in the cover, a rivet passing through said slot and through the plate, a rodieonnected with said rivet, a spring adapted to actuate the plate to its limit of movement defined by 4engagemen't of said rivet With one end of said slot, and a push button on the outside of the cover adapted to actuate the plate to drive.

it to the other end of its movement defined by engagement between the rivet and the other end of the slot.

3. In a sifter box of the kind described,

the combination With a dperforated cover,

s rin -actuated plate, ro connected With t e p ate, and ush button upon the outside -i scribing Witnesses. v
